JOHNSTONE, or summrr, NEW JERSEY, ASSIGNOR TO CAMERON MA- cnnvn compan or BROOKLYN, NEW YORK, A conroaarron or NEW YORK INTERCONNECTED CONTROLLING DEVICE FOR WINDINGAND ROLL-EJECTING MECHA- NISM Application filed May 10,

This invention relates to winding machines for winding a web or webs of flexible material into roll form.

Owing to the fact that machines of this character are now required to handle very wide webs and very heavy rolls it is now the custom to provide roll ejecting means, which latter may take the form of mechanically, electrically or pneumatically actuated devices, examples of such devices being shown in Patent N 0. 1,719,830 and application Ser. N 0. 245,07 5. It will be understood that the paper is being wound at a relatively high speed and that therefore the ejection from the machine of a spinning mass might have highly disastrous results. Conversely the actuation of ejecting means when winding would interfere with the roper winding of the material.

The main 0 ject and feature of the invention is to provide interconnetced or interlocked devices whereby it is not possible to actuate the ejecting means or apparatus when w the winding means or apparatus are active and vice versa.

It will be understood that the nature of the winding means may vary as may the construction of the ejecting means. Some ejecting means are hand-operated and others are power-actuated, and the invention is applicable to either. It will likewise be understood that such controlling devices may vary widely and their detailed construction will depend upon the manner in which power is applied to the elements. For instance, power may be applied mechanically in WlllCh event a clutch or its equivalent would be used, or power may be applied electrically, as by means of individual motors now so commonly used, in which case the control would be exercised by means of one or more switches. Again the control could be exercised over valves that supply fluid pressure. Or, if desired, the winding means could be controlled by a mechanical drive and the ejecting means by an electrical drive or vice versa, or the winding means could be controlled mechanically or electrically and the ejecting means by fluid pressure. All this is well understood by those skilled in the. art and is mentioned 1928. Serial No. 276,685.

here merely vention. v

In the accompanying drawings I have shown what I consider a suflicient number of to indicate the scope of the inpreferred and concrete forms of the invention machine showing the invention in greater detail, a combination electrical and mechanical interlocking being used;

Figs. 4 and Sam detail views of the interlocking devices in different positions; and

Fig. 6 is a view looking in the direction of arrow 6 of Fig. 3.

In the form of the invention shown in Fig. 1, A and A represent winding drums constituting a well-known form of winding means, and associated with these is a winding shaft A and suitable operating means such as an intermediate gear A that drives both drums in the same direction. In the present instance, gear A is driven from an electric motor 1 by means of worm A on the armature shaft of said motor and engaging a worm gear A on the shaft of gear A. The roll ejecting means here consist of a shaft 8 carrying arms 7 which, when swung in the direction of the arrow, engage roll A and eject it out of the valley between the drums. Obviously, shaft 8 is an operating means that can be turned by hand, but, as here shown, it is power actuated from an electric motor 10 on the armature shaft 11 of which is a gear that meshes with ear 9 on'the end of shaft 8. Current is supp ied to motor -1 by any suitable means as generator 2, said generator and motorbein'g included in series in a circuit that also includes circuit breaker 3, armature 4 and solenoid 6. Current may likewise be supplied to motor 10 in any suitable way as by means of generator 12 included in series in a circuit that also includes circuitbreaker 13,

armature 14 and solenoid 5. It will now be understood that when switch 3 is closed a circuit will be established through motor 1 and this circuit will also energize solenoid 6 thereby raising armature 14 and thus preventing the closing of a circuit through motor 10. Conversely when switch 13 is closed a circuit will be established through motor 10 and solenoid 5 will then be energized thereby raising armature 4 and thus preventing a circuit from being closed through motor 1. It is therefore not possible to energize both motors 1 and 10 at the same time.

In Fig. 2, the winding means are the same as before consisting of drums 21 and 22, but

the ejecting means here consist of devices to raise or lower one of said drums. Obviously,

. this could be done by hand, but, in the present case, drum 21 has a pivotal support on the shaft of drum 22 and is carried by an arm 20 connected to rod 24 extending to crank 25. Crank 25 is carried by shaft 26 which latter also has a gear 27 meshing with a gear 28 of motor 10, and this motor is included in a circuit containing generator 12 and circuit breaker 13. In the present case this circuit breaker is controlled by a bellcrank 32 and rod 34 and this bellcrank or hand lever is mechanically interlocked with another hand lever indicated at 29. The two hand levers 29 and 32 have'interlocking latchesor cams 30 and 33 and it will be seen that lever 32 cannot be depressed to close the circuitthrough motor 10 unless lever 29 is in the right-hand osition. Similarly, if lever 32 is down then ever 29 cannot be moved to the left to engage a clutch or close a switch by means of rod 31. In the example here given, rod'34 controls a switch and rod 31 a clutch, but this arrangement can of course be reversed, or both rods may control switches or both may control clutches as the important feature is the interlocking device.

In Figs. 3 to 6 are shown means more in detail whereby either a clutch or a switch can be controlled. The winding and ejecting means here chosen for illustration are those shown in Fig. 1, and 10 indicates the motor for the ejecting means. The winding means are, however, actuated from a pulley 35 controlled by a clutch 36 in a well understood manner. Asher-e shown, clutch'36 is actuated by a grooved collar 37 with which engages the bifurcated end of a lever 38. This lever is carried b shaft 39 from which extends rods 40, 41-an 42, the latter of which is in turn connected to lever 29. Lever 32 is connected to a circuit breaker 13 which controls motor 10 in the manner previous1y indicated. Levers 29 and 32 are rovided with latches or cams 30 and 33in t e manner de scribed in connection with Fig. 2.
